Let's get terms straight. Google is providing private mass transport. It's no more public transport than a charter liquor and gambling bus to Atlantic City. If it was public transport non-Googlers would ride for similar tariffs - ok that's probably inaccurate since poor riders would have their transport subsidized rather than Google's subsidy to those more affluent.
Google's buses are solving more traffic problems in MountainView than San Francisco and relieving the congestion that most impacts commuters from San Francisco to their campus. If the service had to meet the requirements for public transportation i.e. meeting public needs, Google would shut it down.
